Particle density (packed density) - Wikipedia

The particle density or true density of a particulate solid or powder, is the density of the particles that make up the powder, in contrast to the bulk density, which measures the average density of a large volume of the powder in a specific medium (usually air).. The particle density is a relatively well-defined quantity, as it is not dependent on the degree of compaction of the solid ...
